Security fastener including integral plug body and socket body
First Claim
1. A coupler comprising:
- a plug body having a large pushing head member and a pillar member projecting coaxially and downwardly from the lower surface of said large pushing head member; and
a socket body for receiving said plug body, said socket body consisting of a V-shaped guiding tip member having a pair of guide legs arranged below said pillar member with a distance provided therebetween and a pair of flanges respectively connected with said pair of guide legs by way of a pair of side members around said pillar member, said flanges being so arranged that they can be tightly fitted by flexure to one of the plaques to be coupled by the coupler, said coupler further comprising a pair of thin support members extending downwardly and outwardly from said guiding tip member of said pillar member and respectively being connected with said guide legs so that said coupler can be integrally formed of a flexible synthetic resin material with a space provided between said plug body and said socket body.

Abstract
According to the invention, there is provided a coupler which is realized in the form of an integral unit made of an elastic synthetic resin material which is free from any risk of losing any of its components and can be temporarily but securely held in aligned bores of the plaques it is going to couple once it is introduced into the bores so that the plug body of the coupler may be pushed into the socket body with ease. Moreover, since the socket body of the coupler firmly held in the bores of the plaques to be coupled and the plug body pushed into said socket body are connected with each other by means of a pair of thin support members to form an integral coupler unit, said plug body can be pushed into said socket body with a relatively small force to securely rigidly couple the plaques. As there are no parts of the unit which are prone to damage, it is good for repeated use.
